OTHER NAME(S): Clotrim Cream
Clotrim is used to treat skin infections such as athlete's foot, jock itch, ringworm, and other fungal skin infections (candidiasis). This medication is also used to treat a skin condition known as pityriasis (tinea versicolor), a fungal infection that causes a lightening or darkening of the skin of the neck, chest, arms, or legs. Clotrim is an azole antifungal that works by preventing the growth of fungus.
How should I take Clotrim?
Take Clotrim exactly as directed by your doctor. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.
The troches should be allowed to dissolve slowly in your mouth. Suck on one troche at a time until it is completely dissolved, usually 30 minutes.
Do not chew or swallow the troches whole.
The troches are usually used five times a day. Follow your doctor's instructions.
Store Clotrim at room temperature away from moisture and heat.
Before using Clotrim for skin infections
To make sure this is the right treatment for you, before you start using Clotrim make sure that you speak with a doctor or pharmacist:
- If you are pregnant or breast-feeding. Although Clotrim is not known to be harmful to babies, you should only use medicines on the recommendation of a doctor while you are expecting or breast-feeding a baby.
- If you are taking any other medicines or using any other creams. This includes any medicines which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine or cream.
Clotrim, an azole antifungal agent, inhibits 14-α-demethylation of lanosterol in fungi by binding to one of the cytochrome P-450 enzymes. This leads to the accumulation of 14-α-methylsterols and reduced concentrations of ergosterol, a sterol essential for a normal fungal cytoplasmic membrane. The methylsterols may affect the electron transport system, thereby inhibiting growth of fungi.
Safety and effectiveness in pediatric patients have been established for Clotrim when used as indicated and in the recommended dosage.
Getting the most from your treatment
- Remember to wash your hands carefully after using Clotrim, as this will help to prevent the infection from spreading to other parts of your body. Also, use a separate towel to other people until your infection clears up.
- Fungal infections often occur in warm, moist areas of the body. After washing or showering, make sure that all areas of your skin are dried well, particularly areas such as skin folds and between your toes.

Usage in Pregnancy
The disposition of 14 C-Clotrim has been studied in humans and animals. Clotrim is very poorly absorbed following dermal application or intravaginal administration to humans. (See CLINICAL PHARMACOLOGY .)
In clinical trials, use of vaginally applied Clotrim in pregnant women in their second and third trimesters has not been associated with ill effects.
There are, however, no adequate and well-controlled studies in pregnant women during the first trimester of pregnancy.
Studies in pregnant rats with intravaginal doses up to 100 mg/kg have revealed no evidence of harm to the fetus due to Clotrim.
High oral doses of Clotrim in rats and mice ranging from 50 to 120 mg/kg resulted in embryotoxicity (possibly secondary to maternal toxicity), impairment of mating, decreased litter size and number of viable young and decreased pup survival to weaning. However, Clotrim was not teratogenic in mice, rabbits and rats at oral doses up to 200, 180 and 100 mg/kg, respectively. Oral absorption in the rat amounts to approximately 90% of the administered dose.
Because animal reproduction studies are not always predictive of human response, this drug should be used only if clearly indicated during the first trimester of pregnancy.
Is Clotrim safe to take if I'm pregnant or breastfeeding?
Clotrim is very poorly absorbed into the blood and the body after application to the skin or the vagina. Studies in women in their second or third trimesters of pregnancy have demonstrated no ill effects. No data is available in pregnant women during their first trimester. Rats given large amounts of Clotrim via the vagina have demonstrated no ill effects. The oral troche has not been adequately evaluated in pregnant women.
It is not known if Clotrim is secreted in breast milk.
Clotrim may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- unpleasant mouth sensations
Clotrim may cause other side effects. Call your doctor if you have any unusual problems while using this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
Pharyngeal and upper airway irritation is a potential complication. Care should be taken to allow all of the solution to drain from the nasal cavity by keeping the head tilted ventrally over the edge of the table for a short period of time after the procedure. In addition, gauze sponges should be packed into the pharynx during the procedure to catch any of the solution that may leak from the nasopharynx.
In dogs with cribriform invasion, Clotrim may cause CNS irritation, which may result in seizures.
Do I need a prescription for Clotrim?
Yes, for some generic preparations. Lotrimin AF, Mycelex, and Trivagizole are over-the-counter preparations.

Clotrim - Clinical Pharmacology
Clotrim is a broad-spectrum antifungal agent that is used for the treatment of dermal infections caused by various species of pathogenic dermatophytes, yeasts, and Malassezia furfur . The primary action of Clotrim is against dividing and growing organisms.
In vitro , Clotrim exhibits fungistatic and fungic >Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, Microsporum canis , and Candida species including Candida albicans . In general, the in vitro activity of Clotrim corresponds to that of tolnaftate and griseofulvin against the mycelia of dermatophytes ( Trichophyton, Microsporum , and Epidermophyton ), and to that of the polyenes (amphotericin B and nystatin) against budding fungi ( Candida ). Using an in vivo (mouse) and an in vitro (mouse k >Candida albicans .
Strains of fungi having a natural resistance to Clotrim are rare. Only a single isolate of Candida guilliermondi has been reported to have primary resistance to Clotrim.
No single-step or multiple-step resistance to Clotrim has developed during successive passages of Candida albicans and Trichophyton mentagrophytes . No appreciable change in sensitivity was detected after successive passages of isolates of C. albicans, C. krusei , or C. pseudotropicalis in liqu >C. albicans .
Slight, reversible resistance was noted in three isolates of C. albicans tested by one investigator. There is a single report that records the clinical emergence of a C. albicans strain with considerable resistance to flucytosine and miconazole, and with cross-resistance to Clotrim; the strain remained sensitive to nystatin and amphotericin B.
In studies of the mechanism of action, the minimum fungicidal concentration of Clotrim caused leakage of intracellular phosphorus compounds into the ambient medium with concomitant breakdown of cellular nucleic acids and accelerated potassium efflux. Both these events began rapidly and extensively after addition of the drug.
Clotrim appears to be well absorbed in humans following oral administration and is eliminated mainly as inactive metabolites. Following topical and vaginal administration, however, Clotrim appears to be minimally absorbed.
Six hours after the application of radioactive Clotrim 1% cream and 1% solution onto intact and acutely inflamed skin, the concentration of Clotrim varied from 100 mcg/cm 3 , in the stratum corneum to 0.5 to 1 mcg/cm 3 in the stratum reticulare, and 0.1 mcg/cm 3 in the subcutis.
No measurable amount of radioactivity (≤0.001 mcg/mL) was found in the serum within 48 hours after application under occlusive dressing of 0.5 mL of the solution or 0.8 g of the cream.
Only 0.5% or less of the applied radioactivity was excreted in the urine.
Following intravaginal administration of 100 mg 14 C-Clotrim vaginal tablets to nine adult females, an average peak serum level, corresponding to only 0.03 µg equivalents/mL of Clotrim, was reached 1 to 2 days after application. After intravaginal administration of 5 g of 1% 14 C-Clotrim vaginal cream containing 50 mg active drug, to five subjects (one with candidal colpitis), serum levels corresponding to approximately 0.01 µg equivalents/mL were reached between 8 and 24 hours after application.
